PATENTAMT.PATENT OFFICE.
Den Gegenstand vorliegender Erfindung bildet ein Verfahren zur Herstellung feuerfester Produkte, wie Steine, Platten u. dgl., aus einem innigen Gemenge von Sand o. dgl. und Kalk, gegebenenfalls unter Zusatz von Ton, und kennzeichnet sich dadurch, daß die aus dieser Masse geformten Steine usw. in einem und demselben Räume (Kammer) unter Anwendung von Wasserdampf und Feuergasen gehärtet und gebrannt werden.The subject of the present invention is a process for the production of refractories Products such as stones, slabs and the like, from an intimate mixture of sand or the like. and lime, optionally with the addition of clay, and is characterized in that the stones etc. formed from this mass in one and the same room (chamber) below Application of steam and fire gases can be hardened and fired.
Das Herstellen feuerfester Steine usw. aus dem genannten Gemenge in der Weise, daß die Formlinge zunächst an der Luft getrocknet, dann in geeignete öfen eingebracht und hier unter direkter Einwirkung von Feuergasen bei hohen Temperaturen gebrannt werden, ist bekannt.The manufacture of refractory bricks, etc. from the said mixture in such a way that the moldings are first air-dried, then placed in suitable ovens and burned here under the direct action of fire gases at high temperatures is known.
Es ist ferner ein Verfahren bekannt geworden, welches darin besteht, die Formlinge, bevor dieselben zwecks Brennens in die öfen eingebracht werden, nach der in der Kalksandsteinindustrie üblichen Weise in passenden Dampfbehältern mit Wasserdampf zu härten. Hierdurch wird der Vorteil erreicht, daß der Kalk des Bindemittels in kieselsauren Kalk übergeführt wird, welcher eine höhere Festigkeit besitzt, durch die wiederum der Verlauf des nach dem Einbringen in die öfen eingeleiteten Brennprozesses günstig beeinflußt wird.There is also a method has become known which consists in the moldings, before they are brought into the ovens for burning, after that in the Sand-lime brick industry in the usual way in suitable steam containers with water vapor to harden. This has the advantage that the lime of the binder in Silica lime is transferred, which has a higher strength, through the in turn, the course of the firing process initiated after introduction into the furnace is favorably influenced.
Bei dieser Arbeitsweise zur Herstellung feuerfester Kunststeine zeigt sich nun der Übelstand, daß die durch den Dampfprozeß bereits auf höhere Temperatur gebrachten Steine während des Umtransportierens aus dem Dampfgefäß nach dem Ofen bis zur Einleitung des Brennprozesses wieder vollständig erkalten, wobei sich auch der Wasserdampf im Innern der Steine kondensiert. Wird nun mit dem Brennen bezw. mit der Einwirkung der Feuergase auf die eingebrachten kalten Steine begonnen, so ist eine erhebliche Wärmemenge erforderlich, um die Steine auf die schon einmal besessene, aber inzwischen wieder eingebüßte höhere Temperatur zu bringen, und es wird ebenso Wärme verbraucht, um das hygroskopische Wasser, welches gänzlich ausgetrieben werden muß, im Innern der Produkte nur erst wieder auf denjenigen Dampfzustand zu bringen, in dem es sich vor der Erkaltung bereits einmal befunden hatte.In this way of working for the production of refractory artificial stones, the The drawback is that they have already been brought to a higher temperature by the steam process Stones are completely restored during transport from the steam vessel to the furnace until the firing process is initiated cool, whereby the water vapor condenses inside the stones. Is now with the burning respectively. with the If the fire gases start to act on the cold stones that have been brought in, so is one significant amount of heat is required to get the stones on the already owned, however in the meantime to bring the higher temperature that has been lost again, and it also becomes warmth consumed to remove the hygroscopic water, which has to be driven out completely, in the interior of the products only to bring it back to the steam state in which it had already been there before it became cold.
Diese Übelstände werden beseitigt, wenn bei dem Verfahren nach vorliegender Erfindung die aus der Kunststeinmasse geformten Steine, Platten u. dgl. in einem und demselben Räume (Kammer) unter Anwendung von Wasserdampf und Feuergasen gehärtet und gebrannt werden. Dieser Raum ist zu diesem Zwecke gleichzeitig mit Vorrichtungen zur Zuführung des Wasserdampfes, also mit Dampfrohren, die frei oder auch verdeckt gelagert sind, und mit Vorrichtungen beliebiger, geeigneter Konstruktion für die Zuführung der Feuergase ausgestattet und bildet die Kammer eines Kammerofens, RingofensThese inconveniences are eliminated when the method according to the present invention Stones, slabs and the like formed from the artificial stone mass in one and the same Rooms (chamber) hardened and using water vapor and fire gases to be burned. For this purpose, this room is at the same time with devices for Supply of the steam, i.e. with steam pipes that are freely or also hidden, and with any devices Suitable construction for the supply of the fire gases and forms the chamber of a chamber furnace, ring furnace
oder einer anderen für die Ausführung des Verfahrens geeigneten Ofenkonstruktion,.z. B. Rundöfen, Muffelofen usw.or another furnace construction suitable for carrying out the process, e.g. B. Round furnaces, muffle furnaces, etc.
Die Ausführung des Verfahrens geschieht auf die folgende Weise:The procedure is carried out in the following way:
Die Formlinge werden, von der PresseThe briquettes are made by the press
kommend, auf Transportwagen aufgestapelt und mit denselben in die Kammern gebracht.coming, stacked on trolleys and brought into the chambers with the same.
Ist die Kammer besetzt und geschlossen,If the chamber is occupied and closed,
ίο so läßt man den Härtedampf eintreten und die erforderliche Zeit bei der entsprechenden Temperatur auf die Formlinge einwirken. Nunmehr beginnt die Zuführung der Heizgase (Feuergase), durch welche der Härte-ίο so you let the hardening steam enter and act on the moldings for the required time at the appropriate temperature. Now the supply of the heating gases (fire gases) begins, through which the hardening
dampf in der Kammer eine Überhitzung erfährt, womit gleichzeitig das Trockenwerden der heißfeuchten Steine einsetzt. Ist der Dampf hinreichend verdünnt und sind damit die Steine u. dgl. trocken geworden, so beginnt man mit der Steigerung der Heizgasetemperatur, indem man die Wasserdämpfe, entweder vorher durch einen direkten, mittels Schiebers verschließbaren Abzug abströmen oder aber dieselben mit den Rauchgasen des mehr oder weniger ansteigenden Feuers abziehen läßt. Bei Vollfeuer von entsprechender Temperatur wird dann der Brennprozeß vollends durchgeführt.Steam in the chamber is overheated, which at the same time causes it to dry out the hot, moist stones are used. Is the steam sufficiently diluted and so are the stones and the like have become dry, then one begins with increasing the heating gas temperature, by removing the water vapors, either beforehand by a direct, by means of Slider lockable vent or flow the same with the flue gases of the more or less rising fire can be withdrawn. With full fire from the appropriate Temperature, the firing process is then carried out to the end.
Durch Anwendung dieses kombinierten Dämpf- und Brennverfahrens werden nicht nur die obengenannten Übelstände der früheren Verfahren beseitigt, sondern auch noch die Wirkung erreicht, daß das Brennen der Steine u. dgl., die bereits durch die Dämpfung, also durch feuchte Erhitzung, auf eine hohe Temperatur gebracht sind, nunmehr von innen heraus beginnt, wodurch ein Mürbewerden der Steine derart, wie es eintritt, wenn die Feuergase auf trockene Steine u. dgl. niederer Temperatur zur Einwirkung gebracht werden müssen, wie es bei den vorher bekannten Verfahren der Fall ist, vermieden wird.Using this combined steaming and combustion process will not only remedied the above-mentioned deficiencies of the previous procedures, but also those Effect achieved that the burning of the stones and the like, which were already caused by the damping, that is, by moist heating, brought to a high temperature, now from begins from within, whereby a crumbling of the stones as it occurs, when the fire gases act on dry stones and the like at a lower temperature must be brought, as is the case with the previously known methods, avoided will.
